UNITED STATES FRANK H. HOWARD, or R ADING, PENNSYLVANIA.

To all whom it may concern:

Be it known that I, FRANK H. HOWARD, a citizen of the United States, residing at Reading, in thecounty of Berks and State of Pennsylvania, have invented certain new and useful Improvements in I-Beam Travelers, of which the following is a specification. j V a This invention relates to improvements in travelers or load carriers, such as are adapted for moving on an I-beam or track, and the object in the present instance is to provide a device of this character in which provision is made for adapting it to a beam of any width Within the limits usually employed for devices of this kind.

The invention consists in providing means for adjusting the frame to the width de-'.

sired, and I accomplish this by providing cross members slidably engaging the longitudinal members of the frame, and a set of tapered keys for securing the relative frame parts in position. I

"The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in

which Figure 1 is a side elevational view of my traveler.

Figure 2 is an end elevational view there of, with the parts adjusted to accommodate a relatively wide beam.

Figure 3 is a like end View, with th'e parts adjusted to accommodate a relatively nar row beam.

Figure 4 is a sectional view taken through the line 4-4: of Figure 3. p v

The nnmerall designates the longitudinal or side frame members, which carry the trolley wheels 2 and which in turn ride on the I-beam 3. i V

The numeral 4 designates the end or cross members of the frame, and each cross member is formed with an elongated slot 5 which slot is formed with a series of indentations or serrations 6 on its lower surface. The side frame members are s-lidably adjustable on the end frame members and are secured in position thereon by means of a set of wedges 7, which pass through erforations 8 in the side members and w ich wedges are formed with serrations on their under surfaces, 9, adapted to register withthe in dentatiofis in the end frame members.

serrated surfaces of the end frame members and the wedges are both tapered, so that, when the wedges are driven securely into position, there will be asatisfactory contact as between the wedges and the frame, that will insure a secure engagement without the tendency to rock.

It .is evident, that the frame of the traveler will be adjustable to different widths of I-beam on which it is to travel, 1

by merely removing the "wedges, opening the side frame members the desired distance, and then replacing the tapered and serrated wedges.

a By this construction, a traveler will be adaptable to many widths of I-beams.

There are no bolts or nuts to secure, and the ease and speed with which an adjustment can be made are desirable points in the construction.

Having thus described my invention, I

11' In a device of the character described,

a pair of side frame members carrying tr0l-- ley wheels, and formed with perforations in their ends, a pair of end frame members on which the side frame members are slidably mounted, said end frame members having elongated slots provided with serrations, and a series of wedge members having serrated surfaces and adapted to pass through the perforations in the side frame members and to hold the side and end frame'members in adjusted positions.

2. In a device of the character described, a frame made up of two perforated side members and two end members, a set of trolley wheels carried by the side members. elongated, serrated'slots in the end members, and serrated tapered wedges adapted to enter said perforations and hold the side and end frame members in position.

3. In a device of the character described, a pair of end frame members having elongated slots provided with serrations and a pair of side frame members having wedge ture;
